Which statement describes carbon fibre?

Explanation:
Carbon fibre is prized for its very high strength relative to its weight. That combination—being extremely lightweight yet very strong—means structures can be both light and able to bear loads effectively, which is why it’s used in aviation, motorsport, and premium sports gear. The other descriptions don’t capture this key advantage: it isn’t described primarily as heavy, and while it can be stiff and opaque, the standout feature is the exceptional strength for a tiny mass. It can conduct electricity to some degree, but that isn’t the main quality that defines carbon fibre.
